Using two operator triangular wave oscillator circuit
This circuit utilizes two operational amplifiers configured as triangular wave oscillators. It demonstrates a practical application of a relaxation oscillator that employs a voltage comparator to execute the switching function. The schematic in FIG. 2 illustrates the composition of the...
Norton-amplifier
The non-inverting amplifier has a gain of R2/R3 (1 in this case) and produces a voltage of V during a positive excursion of Vin with respect to ground. The inverting amplifier accommodates the negative excursions of V; its gain is...
Op Amp based Hartley oscillator
Construct an oscillator that meets several specifications. The primary requirement is to incorporate exactly one capacitor. Another requirement is to achieve a high quality factor (Q) and produce a sine wave output. The design under consideration is Hartley’s oscillator, which...
Triangular Wave Generator Using Op-amp
This circuit diagram illustrates a triangular wave generating circuit utilizing a pair of operational amplifiers (Op-Amps). The LM741 Op-Amp is recommended for this application. The first Op-Amp, located on the left, functions as a comparator, while the second Op-Amp on...
Square wave oscillator
The hysteresis characteristic indicates that the voltage level transitions to high (H) when the input voltage of the inverter rises from 0 V, and the voltage level transitions to low (L) when the input voltage descends from +5 V. These...
3 Band Graphic Equalizer
This simple equalizer circuit utilizes a single operational amplifier (op-amp) to provide three distinct frequency ranges: low frequency, mid frequency, and high frequency. With the specified component values, the circuit is capable of delivering an approximate gain of +/-20dB at...
Simple Absolute Value Circuit
When the input voltage is positive, the output of ICA is negative, resulting in diode D not conducting; therefore, the output of ICB is positive. Conversely, when the input is negative, the output of ICA becomes positive. Diode D conducts,...
Improved non-inverting integrator
In the circuit depicted in Figure 1, ICla generates the integral term required for operation, but it also inadvertently produces an unnecessary proportional term. This proportional term is countered by IClb, resulting in a pure integral output. If the ratio...
Linear-ic-siren
A low-frequency op-amp oscillator and a voltage-controlled oscillator (VCO), both configured using a single MC3405 dual op-amp and dual comparator, are the primary components in a siren circuit capable of producing various warbles and wails, or functioning as an audio...
